Complete civil packages for battery energy storage near Kingston, NY: pad subgrade and mass grading, foundation excavation, access and crane pads, collection trenching, ductbank, SWPPP, and substation civil.
Backwell contracts complete civil site work packages for battery energy storage developers and EPCs building near Kingston in Ulster County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Kingston is the Ulster county seat at the Interstate 87 Thruway exit 19 traffic circle, with Route 9W, Route 28 and the Rondout waterfront giving highway and barge access, and it is Central Hudson's northern hub. The Central Hudson 345 kV Hurley substation sits just west of the city on Hurley Avenue and is the interconnection point for the proposed 250 MW Alcazar project in the adjoining Town of Ulster. City and near city ground is Hudson lowland lake clay over shale, which means slow draining, shrink and swell subgrade and no infiltration credit for stormwater.

Ulster spans the Hudson lowland on the east and the Catskill front on the west, and the contrast is sharp. The Kingston, Hurley and Saugerties lowland sits on Ordovician shale and greywacke with extensive glaciolacustrine cover from Glacial Lake Albany, mapped in Hudson, Vergennes, Rhinebeck, Kingsbury and Livingston type clays: fine textured, calcareous, somewhat poorly to moderately well drained, very slowly permeable and prone to shrink and swell. Stratified drift terraces follow the Esopus and Rondout creeks, with Tioga and Wayland alluvium on the floodplains. West and south the land rises into Catskill sandstone, siltstone and conglomerate, where Arnot soils sit on bedrock at 10 to 20 inches and Lackawanna and Wellsboro carry a dense fragipan starting between roughly 17 and 36 inches. Shawangunk conglomerate forms the hard ridge behind Ellenville. Seasonal water perches above the fragipan and above the lake clays. Frost design depth is commonly taken at 42 to 48 inches subject to the building department.
On the lowland sites that carry the large projects, the lake clays are the controlling condition. They have very low permeability, so stormwater design cannot rely on infiltration and treatment falls to lined basins and mechanical practices. They lose strength rapidly when wet, so haul roads and laydown need a stone section placed before general earthwork and kept in service through the job, and pad subgrade needs proof rolling with undercut and replacement where it pumps. Shrink and swell argues for a thicker free draining structural section under enclosure pads and for burying cable below the active zone. Where the layout climbs onto Catskill ground, shallow Arnot profiles put sandstone within two feet of grade, and the Lackawanna and Wellsboro fragipan acts as an aquitard that must be broken or drained at the pad perimeter rather than simply covered. A 15 acre site holding 250 MW means dense equipment spacing, so trench congestion, grounding grid layout and fire apparatus turning movements drive the grading plan more than bulk cut and fill volume does.

Concrete is placed by our subcontractor partners under the same contract, so the foundations follow the earthwork without a separate award. We price the civil package as one scope under one contract, which gives the EPC a single point of responsibility for the civil critical path instead of managing separate clearing, earthwork, and underground subcontracts.
Battery storage in New York is governed by Section 1207 of the 2025 Fire Code of New York State, which the State Fire Prevention and Building Code Council adopted on July 25, 2025 with an effective date of December 31, 2025. Section 1207 carries material based on the 2023 edition of NFPA 855 and renumbers what the 2020 code placed at Section 1206. Systems must be listed to UL 9540. Large scale fire testing under UL 9540A, reported to and approved by the fire code official, is what permits reduced separation distances and quantities above the table limits, and a hazard mitigation analysis is required to exceed the maximum allowable quantity. Outdoor installations carry a ten foot clearance to lot lines, public ways, buildings, stored combustibles, and other exposure hazards, with ten feet of combustible vegetation cleared on each side. New York added a mandatory peer review at Section 1207.12 for systems above the Table 1207.5 quantities, covering the site plan, the emergency operations plan, and the UL 9540A report. Those provisions fix pad layout and access road geometry before any earthwork is priced.
Battery storage siting in New York runs on the Fire Code of New York State, which adopts the International Fire Code provisions for stationary energy storage, together with NFPA 855 and the UL 9540A test reporting the authority having jurisdiction will ask for. The civil consequences are set early and they are ours to build.
We build to the approved civil drawings and the fire code commentary that comes with the permit. We do not stamp the design.
Local law. As of September 2026 Hurley and Gardiner carry active utility scale battery storage moratoriums. Saugerties has taken the opposite route: the building department determined that battery storage is allowed in the industrial zone and the zoning board of appeals upheld that determination, sending KCE NY 34 to planning board review rather than a moratorium.
Backwell superintendents, project managers, and lead operators run every site. We mobilize company equipment for the core scope and scale each project with leased production fleets, qualified regional subcontractors, and agency-placed field staff, all under Backwell supervision and a single contract.
Contractor licensing. New York does not issue a statewide general contractor license for commercial construction. Licensing is handled locally, so individual cities, towns, and counties may require contractor registration or a local license, and a few trades are licensed at the state level, including asbestos handling and crane operation. Separately, contractors and subcontractors performing public work, and work covered by Article 8 of the Labor Law, must be registered with the New York State Department of Labor under its statewide contractor registry, which took effect December 30, 2024. Owners, EPCs, and integrators on battery storage projects will typically ask for that DOL registration number along with insurance and, where required, bonding.
Construction stormwater. SPDES General Permit for Stormwater Discharges from Construction Activity, permit number GP-0-25-001, issued by the New York State Department of Environmental Conservation. It took effect January 29, 2025, replacing GP-0-20-001, and runs through January 28, 2030. Coverage is triggered at one acre of soil disturbance, or less if part of a larger common plan, and requires a Notice of Intent plus a SWPPP prepared and implemented under the DEC design manual. Coverage under the prior permit did not carry over automatically, so active sites had to refile. Backwell carries the SWPPP scope, installs and maintains the controls, keeps the inspection log, and closes the permit out with final stabilization.
Prevailing wage. Standalone battery storage sits outside New York Labor Law Section 224-d. That section applies to a covered renewable energy system as defined in Public Service Law Section 66-p, and that definition lists generating technologies only, so energy storage is not included and Section 224-d contains no storage clause. Prevailing wage still reaches many storage projects by other routes. Labor Law Section 224-a expressly excludes an energy storage system with a capacity equal to or under five megawatts alternating current, which means a larger storage system on a privately contracted project that meets the public funds and cost tests can be covered. The Public Service Commission order of June 20, 2024 establishing the updated energy storage goal states that projects of one megawatt alternating current and larger will be subject to prevailing wage requirements, so incentivized projects carry it as a program condition rather than by statute. Storage co-located with a covered renewable generator follows that generator. Separately, contractors and subcontractors performing public work, and work covered by Article 8 of the Labor Law, must be registered with the New York State Department of Labor under the statewide contractor registry effective December 30, 2024. The applicable trigger should be confirmed project by project. Backwell produces certified payroll, pays the applicable wage determination, and supports apprenticeship labor-hour compliance.
